TRUSTED TO PERFORM

*In a test of the oil’s strength across a variety of engine speeds, the Castrol EDGE range average metal-to-metal contact is 40% lower than a leading competitor.
**We asked a third party laboratory to test the Castrol EDGE range using our Maximum Endurance Test. On this test Castrol EDGE was proven to be on average 35% stronger for longer compared to a competitor brand from another major lubricant supplier.
